The frame of WIAWISAerobike, WAWS-1, is applied aeromechanical plan overall. Contrary to former Airfoil, WIAWISAeroTubingstructure used Truncated Airfoil satisfies both reducing the effects of wind resistance and rigidity against impact. DownTube and Chain Stay have an asymmetrical structure to make balance of power and tapered Head Tube was upgraded to improve handling and cornering better in riding.

LIGERO NANO is the bike credited for the best performance. The weight off the frame is realized at 890g through the minimalized design guide, high elasticity stiffness and the excellence for nano-carbon. LIGERONANO is born for the rider who challenges their own limitations.

CULs is the World's first mass production type and ultralight frame showing carbon and manufacturing technologies. We were able to produce a safe and durable bike by focusing on Nano Carbon technology, High elasticity of carbon and remarkable pattern minimizes connecting parts. Surprisingly light frame guarantees that it provides the best riding performance and excellent riding quality.
